Upper and lower low-profile polyurethane roller spin on sealed bearings
and keep your chain securely wrapped around the chainring delivering
consistent and reliable performance. The polyurethane compound found in
the S4 rollers was extensively tested to deliver the best blend of
quiet operation and long term-durability. The polycarbonate bash guard
utilized in the S4 guide protects the chain, rollers, and backplate
from contact with rocks, roots, logs, or anything else for that matter
and directs impact away from the frame.
